Abstract
MULDER'S work1 has shown that whereas macro-elements did not alter the amino-acid composition of potato protein, they did significantly alter the amino-acid composition of its soluble non-protein nitrogenous fraction. The influence of micro-nutrients on the amino-acid composition of plant proteins has not been properly studied, although there is evidence which suggests it might be appreciable2. There is, in fact, reason for believing that micro-elements may alter the relative proportions of the amino-acids in plant proteins. If such is the case, this effect would be of great interest in animal and human nutrition, especially since deficiencies in trace elements are widespread3, as is infant protein malnutrition (kwashiorkor), which appears to be primarily the result of amino-acid deficiency4.
